Two years ago i bought a 1970 455 that had sat on the ground in a shed in Michigan since 1983. When i pulled the drain plug I got out about 3 qts of oil, black but not as bad as i expected. Some vermin had gotten into the intake and a couple of the open head intake ports and left some straw and acorns but the pan had oil…….

^^ that's what's tough about this. The OP mentions pulling it out so assume it was in something. Where does 6 qts of oil go? Wonder if there was evil afoot somewhere...image if it happened way earlier on and the OP started it up with no oil... Just saying...

Hopefully you didn't have any enemies and one of them slipped over and drained your oil on the ground to get at you.

Parked outside you can leak 6 quarts of oil on the ground, and over 10 years, and there won't be any trace of it. A rust hole in the pan could easily empty the pan over 10 years.
Microscopic bacteria actually will eat petrochemicals over time, that is what happens to oil spilled in the ocean by off shore rigs when the leak millions of barrels into the ocean. As I said, take it out and inspect it if you really want to preserve the engine, If you don't really care about it, roll the dice with flushes, etc. Just like Dirty Harry said, "Do you feel lucky"? The thing is, if you spend time and money flushing the engine out, put oil in it, only to find a pin hole due to rust from the inside, now you're back to pulling the pan anyway, unless you want to use an epoxy (JB Weld) to stop the leak. Lots of ways to go, but many are sketchy, and you're guessing, and testing your good fortune. I'll add that I have been down this road before, and tried the cheap, easy way, and it cost me money, and time. So speaking from someone that has more bad luck than good, I'd have a look see inside. Ya ever notice that every time VGG does one of these find a car, get it running, and drive it back home, he either doesn't make it, or when he starts running the car on the road, (after his low dollar "Restoration"), it has a blue cloud behind it? Roadkill has about the same results, sometimes they get lucky, and all the stars, and planets align, but I see more failures than successes..... |

Will the engine turn over by hand??

If you really want to preserve the 400, I agree with everyone who says pull it and open it up. OTOH, if you don't really care about that motor and you just want to see if you can get it to run without killing it, then you could try to flush it. But if I had to bet, I'd bet it won't survive a flush and run. Just to point out the obvious, in those "will it run" videos, they don't really care if it runs and survives or not. Either way they get the clicks.

I’d pull the plugs. Oil the cylinders with my favorite spray. Pull the valve covers. Wash over both heads with Diesel or kerosene and let it run out the bottom till “clean”. Fill it with your favorite high zinc oil, new filter, spin it over a few times to prime and, bust it off. If it lives great. If not, you now have bonafide reason to open it up. It’s gonna run though. Then you’ll see where the oil is going.

At present, any place I own that I could work on it, is filled with two snowmobiles, a quad, a sxs, and another car. |

Anyway, at this point it is what it is. Quite obvious there's no oil in there, so I will work from that. |

It was never drained on the ground or I'd have seen some sign of it, and it's highly unlikely someone drained it and took the oil away. And considering where it was parked, it would be very highly unlikely someone would do it, or even have a reason to do it. |

I may go the flush route to start. My goal was to get it started before I put any time and money into it. If I have to tear apart either engine, it would like be the 455. |

I did not try it. That was going to be my next step after I changed the oil.

You can buy a borescope cheap on Amazon for $40. send that up the drain hole, down a pushrod hole, in the gas tank. Should confirm any suspicions that you need to pull the motor and freshen everything.

Now there's a good idea.
